ture for carrying out a plurality of associ? ated operationsfor grinding, and crushing fresh or dried fruits or vegetables and for. straining and filtering the product, the

grinding and straining devices being. located in longitudinal alinement with the ends abutting, and with hinged connections between the members for'moving thestrainer out. of operative relation with the grinder and. crusher. v 1 l A further object of the invention is the pro-,-

vision of a device for obtaining fluids contained in fruits or vegetables in which 'a' drum I has a longitudinally disposed spirally are ranged grinding device in axial alinement with a housing provided with a strainer, the

adjacent'or abutting ends of the drum and housing being hii'i'gedly connected together, whereby the housing carrying a stralner may of the drum so that the pulp container Within the housing or drum may readily be removed.

This invention will be best understood from a consideration of the following detailed description in connection with the accompanying drawings; nevertheless 1t 1s to be under-- stood that the invention is not confined to the disclosure being susceptible of such changes as shall 'define no material departure from the salient features of the invention as ex pressed in the appended claims.

In the drawings 1 7 Figure 1 is a vertical section of the device constructed according to the principles of our invention,

Figure 2 is a longitudinal horizontal section of the device,

Figure 3'is a view in elevation of the units connected in'gang,

. Figure 4 is a vertical transverse section" taken along the line 4-4 of Fig. 2,

Referring more particularly to the drawings, designates a drum having its axis fed on asleeve21 secured to the shaft 15.. The

In this passage is mounted a cone-shapedmember 27 forming a 'fruitj crushenj,,Crushing effect. is provided by the restricted space 28 located adjacent-the outer; end of the member 27,'and"the outer end ofthe' passage 26.

It will be libted that the "sidewalls ,of the member-.27 .a're inclined ata greater angle 7 ing 29 through which th'eground food and juices are adapted to'be'passed before they enter the restricted passage' 26. The conically shaped member 27-is secured to the shaft 15 and is vrevolved thereby.

A housing 30 is provided with ears 31 to which "is pivotally connected an arm 32. Arms 33 are' pivotally connected at 34 to the ar1n'32, while the arms 33 are pivotally con- 7 nectcd at 35 to the inner end ofthe drum 10 The end of the housing 30 is provided with an ear 36 adapted to aline with an ear 37 on the drum l0, and a bolt 38 is adaptedto maintain the ears 36 and 37in spaced relation V 42 adiaeentthe' periphery through whichthe.

finely ground and crushed pul is' forced in close contact with .arevolving lade 43,- said blade being secured to a shaft 44 driven by 'apulley 45 exteriorly of the housingfl30 and having an end, as shown at'46, mounted in the hub or hearing 23 of the disc 24;

'Ascreen or strainer47 is' mounted infthe housing 30 and-spaced from the housing to providean' annular chamber 48 into which thejuices fall and is discharged through 'a screen 49 and a discharge spout 50.

v The sleeve 51 1s secured to the shaft 44 and from which projects radially a'plural-- 'lty ofbeater arms 52 which are revolved in the strainer 47 forthoroughly beating up and agitating the pulp. The-outer ends of these beaters, as will be noted, are in close association with the strainer 47. The drum 10 is supportedby legs 55.secured at 56 to the si e walls of the drum.- Cleats 57 said in m taining the screen 47 in spaced re,-

lation with the inner wall of the housing 30.

Re'ferring'more particularly to- Ifig. I}, it will be noted that a gang of the frult gr1nd-' ing, v crushing and straining devices are combined and. in which the discharge spout 50 discharges-into a'hopperv 60 of a drum 10. The housing has a discharge spout and has its lower end in substantially the same horizontal plane as the'upper end of a hopper This hopper isin communication with the drum-10 while the housing 30? discharges its liquid contents through. thedischarge' spout 50*. In each of these cases the housings 30, 30", 0,130", are 'respec tively swingable on the hinged mounting 34 between said housing and the respective drums 10,10", and 10".

The operation of my device is-as follows:

The fruitlor Vegetables are placed the hopper 12 and are passed through the opening ll-into the drum 10 where the spiral member; 20 grinds the fruit and moves it with sufiicient pressure towards the inner end of the drum to force it through the slanted space 29 into the cone crusher 27,

- and the conically shaped passage 26. As the ground materials pass the restricted space 28 they are thoroughly crushed before they association with the. screen 47 so that the 'juicesand the fine pulp are moved in the screen thereby straining the juices which are discharged through the conduit if; 1,730,067, f
